Uploading a very large file

[mech1EC4JM]

Hi,

I have a proprietary STP file from a supplier that I would like to open in Fusion to extract and modify some components. The problem I'm having is that the model is extremely detailed, and is around the 850MB mark in size.

I haven't had any luck uploading it to Fusion, either through Fusion itself or through the web interface. Fusion gives me a simple "Failed" warning in the upload window, and the web interface shows "Unrecoverable exit code from extractor: -1073741852".

Opening the file shouldn't be a problem - I've got a good machine with 24GB of RAM (currently waiting for an upgrade to 32GB) and I've had big files in Fusion before. Previously I've had a colleague convert the files to .3dm in Rhino, which for some reason allows me to upload them through Fusion. However we use Fusion for everything now so that's not an option anymore.

Does anyone have a suggestion on how to get this file uploaded so I can open it in Fusion?

Thanks for your time.

AFAIK Fusion 360 is not really designed for objects with 10k (???) faces. I would recommend to pre-process the file in e.g. Meshmixer.

is this a solid model or a mesh ?

Usually .stp files are used for solid models (BRep & NURBS) but they can also can contain meshes.

Rhino is a pure surface modeler AFAIK and only exports surfaces that would then have to be stitched into a solid in Fusion 360.

850MB, however, is an extremely large file or Fusion 360 to chew on.

STP.. sry. I somehow was thinking about STL. Sry - ignore my post.

Thanks for the info. I would assume the file is a solid model but I really don't have any way of checking that without opening it.

Previously my colleague would import the STP file into Rhino, then save it as a .3dm file. This could then be uploaded and opened directly in Fusion 360. The models converted in this way opened in Fusion with regular assemblies made up of bodies - not meshes.

The last time I did this was with a 750MB file, so I was hoping it wouldn't be too much to stretch that by another 100MB! If this is just a limitation on Fusion I'll need to look at other options.

Hi mech1EC4JM,

I understand this is proprietary data, but if you could share with me privately we can see if we can help you out.

you can send me a personal message through here or email me directly at Jamie.Gilchrist@autodesk.com

Hi Jamie,

Thanks for the help. I've sent a link with the file to you directly.

I've found a (partial) fix for now; I downloaded the trial of Inventor, saved the file as a STP which reduced it to just over 300MB, and it can now be uploaded and opened in Fusion. From what I can tell there's no detail missing, so I'm not sure how simply re-saving as a STP reduced the filesize by 500MB, but it works. Still, if there's a more permanent solution (the trial is only good for 30 days, then I'm stuck again!) I'd love to hear it.

I've been searching through threads on this subject of max file size and not once has seen a solid answer on what the max upload file size is. I've got a 180MB IGES file that is of surfaces and solids, and Fusion is choking at about 35-40% of the way through, after less than 30-minutes. I'm not getting any errors, just no progress whatsoever, for hours now.

So what is the theoretical upload file size limit???

50mb, 100mb, 500mb?

Is there not a clear answer for this, to keep us from wasting our valuable time trying to upload something that is not going to work?

Running into same issue. 965MB machine file. I can't even open it let alone upload it.
